Specification of Letters Patent.

Patented Feb. 24, 1914.

Application illed November 9, 1910. Serial No. 591,486.

To all whom it may concern.

Be it known that I, Wxuas M. Tnoxrrsox, a citizen of the United States, residing at. Lancaster. in the county of Lancaster and State of Nebraska, have invented new and useful Im vrovements in Wagons, of which the following is a specification.

This invention relates to improvements in the construction of wagons havin means for elevating the front bolster. wien the wagon is turned in either direction, to permit the corresponding front wheel to move beneath the wa on body.

The object o .the invention is to provide a specific form of connection between the front axle and bolster, which is adapted to maintain the same in constant parallel relation durin vertical displacement of the lat.- ter. and wiiich will prove strong and durable under the most trying conditions of usage.

The invention consists in the features of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference bein had to the accompanying drawing, in w rich:

Figure 1 is a side elevation of a wagon constructed in accordance with the invention, showing the front axle turned in one direction; Fig. 2 is a central, longitudinal sectional view taken through the forward portion of the wagon and, Fig. 3 is a detail view of the front. olster.

' In the accompanyin drawing,thc numeral i' designates the reach no of the we on whose forward end is mounted within a iorizontal slot. 8" provided centrally in the front axle i and is provided with a vertical opening T rotalably receiving the vertically disposed hollow post. 8, which latter extends upwardly through the axle t to a considerable distance above the same. The front hodv bolster 14 is provided centrally with a vertial bore opening through its under face for the reception of the upper end iortion ol' the hollow post B. The upper cm of the bore. i is reduced as at for the reception of a king pin 17 which depends into the hollow post, the annular shoulder iii provided at the junction between the main )ortion and the reduced portion of the ho stcr bore bcin disposed at the level of the elevated active faces of the fifth wheel 10, when the roller wheels 13 of the body elevating device are dis )osed within the depressions 12 of the fift 1 wheel.

From the above description taken in connection with the accompanying drawings, it will be noted, that when the front axle is rotated aml the body bolster is eonsequentl y elevated by the means provided for the purpose, the said bolster and the king pin will ac guided in their upward movement. by the hollow post 8. so that a strong connection will be maintained between the front axle and the bolster at all times.

From the foregoing description, the simplicity and advantages of the structure just described will be a 'iparent to those skilled in the art to which tlic invention appcrtains, it being noted that my improvement may be applied readily to vehicles now in use without. materially changing the (.OllSil'llCilOll of the same.

Having thus described my invention, what I claim is:

1. The combination with the front. axle and bolster of a wa on of the class described, of a vcrtica lv extending hollow post mounted in the said axle and projecting upwardly therefrom, the said bolster being provider with a vertical bore opening through its umler face for the rotatable and slidable reception of said hollow post, and a king pin provided in said holster bore coucentrie therewith for reception within the hollow post.

2. The combination with the front axle and bolster of a wa on ot' the class dcscribcd, the said axle being provided with a horizontal slot for the reception of the reach bar of the wagon, of a vertically extending hollow post. mounted within the said axle and extending through the slot. for engagement with the reach bar, the said post projecting upwardly from the axle, the milder being provided with a vertical bore opening through its end face for the rotatable and slidable reception of the said post and being provided with a smaller opening communicating with the a nun end of the said bore, and a king pin lit apted to depend through the last-named opening into the bore of the bolster concentric therewith for reception within the hollow )ost.

in testimony whereof alhx my signature in presence of lwo witnesses.
